Another bug?

ConditionalReader:

TYPE string
DEFAULT this_is_the_default

1 test
2 string
5 
8 testing

This throws an error that it doesn't understand line 6 (the one with frame 5). Note that there's just one space after 5. The space is there to separate the frame number from the value. In this case I want the value to be an empty string.
Note that setting the default string to empty *does* in fact work (with just the one space after "DEFAULT"), but the exact same thing *does not* work for the individual frames.

edit:
This example script goes with the above "test.txt" text file, for testing purposes:

ColorBars
Trim(0,500)
ScriptClip("Subtitle(String(myvar))")
ConditionalReader("test.txt", "myvar", false)
